I had a request for a tutorial on a fishtail braid, so I hope this makes sense!!!
First, separate your hair into two sections:
Now, take a small section from the outside of the left side, and cross it over to the inside of the right side. Now repeat on the right side, and keep doing it over and over til you get to the bottom. I took pretty big sections with this braid because a.) I'm lazy and b.) I didn't have a lot of time this morning. Shocking, I know.
Here's the finished product! If you want, you can take smaller sections and it looks more intricate.
This took about 3-4 minutes.
